A method for manufacturing a display module includes preparing a display module comprising a plurality of layers and forming a through-hole in the display module. The forming the through-hole includes performing a first irradiation process of irradiating a first laser beam along a first boundary defining the through-hole, performing a second irradiation process of irradiating a second laser beam along a second boundary after the first irradiation process, and performing a third irradiation process of irradiating a third laser beam along a third boundary after the second irradiation process. A time interval between the first irradiation process and the second irradiation process may be different from a time interval between the second irradiation process and the third irradiation process.

Display module, method for manufacturing display module, and laser machining method

A method for testing a display module may include providing light to the display module, obtaining an image of the display module, measuring a first center of a hole in the display module, measuring a first distance from the first center to an edge of the hole, measuring a second center of a closed line formed by a signal line of the display module, measuring a second distance from the second center to the signal line, calculating a third distance between the first center and the second center, and comparing the second distance with a sum of the first distance and the third distance.

Apparatus for testing display module and method for testing display module

A display device includes: a display panel configured to display an image; a window panel covering the display panel, and including a display area configured to transmit the image and a non-display area surrounding the display area; and an adhesive layer between the display panel and the window panel, wherein the window panel includes: a window substrate facing the display panel; a protective layer on a portion of a surface of the window substrate in the non-display area; and a light blocking layer on the protective layer, wherein the protective layer is an organic-inorganic composite layer.

Display device

A display device includes: a display panel configured to display an image; a window on the display panel, the window having a display area at which the image is displayed and a non-display area around the display area; and a first adhesive layer between the display panel and the window, wherein the window includes: a window substrate on the display panel; a first hard coating layer at a first surface of the window substrate; a second hard coating layer at a second surface of the window substrate opposite to the first surface; a protection layer on the first hard coating layer; an auxiliary adhesive layer on the second hard coating layer; a base film on the auxiliary adhesive layer; and a second adhesive layer between the auxiliary adhesive layer and the base film.

Provided is a display device including a display panel configured to display an image, and a window panel located on the display panel, the window panel having a display area for transmitting an image displayed on the display panel, and a non-display area surrounding the display area, wherein the window panel includes a window substrate, and a print layer on a lower surface of the window substrate in the non-display area, and including a silicon-based polymer or a fluorine-based polymer.
